   int data1,
   int data2,
   int data3,
   int data4,
   byte precision,

Parameters

data1

Low number component. The 0-31 bits of the internal representation

data2

Middle-low number component. The 32-63 bits of the internal representation

data3

Middle-high number component. The 64-95 bits of the internal representation

data4

His number component. The 96-127 bits of the internal representation

precision

The precision of the TdDecimal

scale

The scale of the TdDecimal

TdDecimal uses four 32 bit integers to internally store the number. The four integers will represent the decimal as a scaled 128 bit integer --the decimal point has been removed by multiplying the number by 10 to the power of the scale. This decimal is stored this way because it is very easy to perform operation on the decimal. The precision and scale are stored separately within TdDecimal.

The four number components that are passed in consist of the following:

• data1 contains the low order bits
• data2 and data3 consist of the middle order bits
• data4 contains the high order bits

The following is an example of setting up the number components, and then invoking the constructor.

// Decimal Number:  82985000914920.733988
// Hex Representation:      4 7FA5F2A8 A350FD24
TdDecimal value01 = new TdDecimal(unchecked((Int32)0xA350FD24), (Int32)0x7FA5F2A8, (Int32)0x00000004, 0, 20, 6);
            
// Decimal Number:      -4352.68
// Hex Representation:  ffffffff ffffffff ffffffff fff95bbc (represented in two's compliment form)
TdDecimal value02 = new TdDecimal(
                            unchecked((Int32)0xfff95bbc), 
                            unchecked((Int32)0xffffffff, 
                            unchecked((Int32)0xffffffff, 
                            unchecked((Int32)0xffffffff, 
                            6, 2);
